DOUBLING AND SHEARING APPARATUS.
sencrrrca'rrcu forming @sa of Letters Patent No. 695,873, dated March 18, 1902- Application filed July 13. 1901. Serial No. 63,222. (No mndel To @ZZ when?, may concern:
Be it known that I, CHARLES WV. BRAY, of Pittsburg, Allegheny county, Pennsylvania, have invented a new and usefulDoubling and Shearing Apparatus, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a top plan view showing apparatus constructed in accordance with my invention. Fig. 2 is a side elevation of the same,partly broken away. Figs. 3 and 4 are front elevations of the doubling apparatus, showing the parts in diiferent positionsgand Figs. 5 and 6 are vert-ical cross-sections of Figs. 3 and 4, respectively, the rolls being shown diagrammatically.
My invention relates to the doubling and shearing of plates, especially blackplates used for tinning; and its object is to provide simple and effective apparatus of this character which will act upon the sheets as they emerge from the feed-table of the finishingrolls and in which the steps, while carried out automatically, are entirely under the control of the operator.
In the drawings, 2 represents a feed-table leading from the finishing-rolls of a feed-mill, this table being shown as provided with sprocket-chain carriers 3, movable over end sprocket-wheels 4. The doubling apparatus 5 is arranged in line with this feed-table and is provided with a series of feed-rollers 6, through which the sheets pass over a guideplate 7. These rollers, which are positively driven by sprocketchain 8 engaging the sprocket-wheels at the ends of their shafts, feed the sheets against the adjustably-fixed stop 9 at the rear end of the doubler table. Above this feed-table and about centrally thereof I place two pairs of doubling-rollers 10 10 and 11 11, whose bearings are adjustable horizontally within bearingboxes 12 upontheframe,asshowninFig.2. Thelower rolls 10 10 are provided with registering circumferential recesses 13, which are arranged to receive pusher-bars 14, adjustably supported in a doul )lingblade 15. The upper ends of the bars 14 are reduced or made thinner, as shown in Figs. 5 and 6, and these bars are provided with vertical slots, through which extend pins 16 on the doubling-blade. The doubling-blade and the pusher-bars are raised and lowered by means of wedges or inclined blocks 17 which bear upon the rollers 1S at the lower end of the pusher-bars, and by wedge-blocks 19, which bear upon rollers 20, mounted in pairs at the lower ends of the legs 21, projecting downwardly from the doubling-blade. The wedge-blocks are mounted upon a horizontal slide 22, which is reciprocated horizontally by pivotal connection 23 with a ram acted upon by cylinders 24 and 25, respectively. The bars 14 are guided within the blade during their movement, and the blade is guided between the side members 26 by means of a pin 27, which passes through an inclined slot 2S in the bending-blade.
The upper doubling-rollers l1 are plainfaced, and above them is mounted a deiiector or shield 29, which is inclined, as shown in Fig. 2.
The shear 30 is arranged in tandem with the upper doubling-rollers and is provided with a table having rollers 3l and an adjustable stop 32, controlled by hand-lever 33.
The rollers of both feed-tables, as well as the doubling-rolls, are driven from an electric motor 84. This motor is connected by a slowmotion gearing with a constantly-rotating shaft 36, carrying pinion 37, intermeshing with pinion 3S upon the shafts of one of the lower rolls 10.- rlhese lower rolls are geared together, and at the opposite end one of the upper rolls'll is provided with a pinion 39, which engages a corresponding pinion on the end of one of the lower rolls 10. Upon the shaft 36 are loosely mounted two clutch members 40 and 41, each carrying a sprocket- Wheel. The sprocket-wheel upon the clutch 40 is connected by sprocket-chain 42 with a similar wheel upon the shaft 43, which is the shaft of the rear feed-roller of the lower table. The other clutch member 41 is connected by chain 44 to the shaft 45, which forms an extension of the shaft of one of the feed-rollers 3l of the upper table. This shaft is provided with sprocket-wheels 46 and 47, connected by suitable chains to sprocket-wheels upon the other rollers of this table. The clutch members 40 and 41 coact with sliding clutch members 48 and 49, .which are keyed to the shaft 36 and may be actuated by bell-crank levers 50 and 51, having operating- links 52 and 53.
In the operation of the apparatus the sheets pass from the feed-table 2 onto the feed-table vof the doubling apparatus and are fed along thereby until the sheet engages the adjustable stop 9. At this time the doubling blade and bars are in the position shown in Figs. 3 and 5. The operator then admits iuid to one of the ram-cylinders, and thereby forces the slide carrying the wedge-block endwise, thus forcing the blade and bars upwardly. When the rollers 2O reach the apices of the inclined faces 19, the movement of the blade ceases, while the further movement of the ram forces the bars 14 upwardly to bring the bent sheet into the bite of the lower pair of rolls. The bars are then in the position shown in Figs. 4 and 6 and the sheet beingvdoubled upwardly at its middle portion feeds upwardly as a twoply sheet between the upper rolls, andbeing acted upon by the detlector 29 it falls forwardly u-pon the feed-table of the shear. The feed-rollers of this table then being actuated, the sheet is fed forward until it meets the stop, when the rear end of the doubled sheet is trimmed oit. The stop is then lifted and the sheet fed forward to any desired point. The operator throws in or disengages the table-clutches, as desired, as the sheets are fed from the table 2, and the action of the apparatus is rapid and eflcient.
The advantages of the invention llow from the peculiar doubling mechanism I employ and also from the arrangement of the doubling mechanism iu connection with the shear mechanism.
Many changes may be made in the form and arrangement of the parts without departingrfrom myinvention.
I claiml. In doubling apparatus, a pair of doublingrollers arranged horizontally, a table or support for the sheet beneath the said rollers, an opening in the support registering with the rollers, a pusher-blade movable through the opening and mechanism for moving the pusher-blade vertically to force the intermediate part of the sheet lying on the support upwardly between the doubling-rollers; substantially as described.
2. In doubling apparatus, apair of grooved rollers, and a pusher having parts arranged to enter the grooves and force the intermediate parts of the sheet between the doublingrolls; substantially as described.
3. In `doubling apparatus, a pair of grooved rolls, a pair of plain-faced rolls in tandem therewith, and a pusher arranged to force the intermediate part ot the sheet into the bite of the grooved rolls; substantially as described. l
4. In doubling apparatus, a feed-table, a stop, a pair of doubling-rollers mounted over the middle part of the table, and a pusherblade arranged to force the intermediate part of the sheet upwardly between the rolls; substantially as described. v
5. In doubling apparatus, a feed-table, doubling-rollers thereover, mechanism for forcing the intermediate part of the sheet upwardly between the rollers, a feed-tableabove and to one side of the rollers, and a deilector arranged to cause the rising doubled sheet to drop upon the upper feed-table; substantially as described.
6. In doubling apparatus, a feed-table having a stop, two pairs of doubling-rollers arranged above the intermediate part of the table, the lower pair having grooves while the upper are plain-faced, a vertically-movable pusher-blade arranged to bend and force the intermediate part of the sheets between the lower pair of rolls, and mechanism for driving the rolls; substantially as described.
7. In doubling apparatus, a pair of grooved rolls, a blade movable toward and from the bite 'of the rolls, and pusher-bars arranged to project beyond the blade and enter the grooved portions ot the rolls; substantially as described.
8. In doubling and shearing apparatus, a pair of doubling-rolls, mechanism for bending and feeding the intermediate part of the sheet thereinto, a shear-table arranged to receive the sheet from the bending-rolls, and a shear arranged to trim the ends of the doubled sheets; substantially as described. i
9. In doubling and shearing apparatus, a doubling feed-table, doubling-rolls above the saine, an upper deilector, a shear feed-table upon which the deilector guides the doubled sheet, a stop on the shear-table, and a shear arranged to trim the edges of the sheet; substantially as described.
l0. In doubling apparatus, a pair ofgrooved rolls a blade movable toward and from the bite of the rolls, pusher-bars movable relatively to the blade, and mechanism for moving said bars relatively to the blade and into the grooved portions ot' the roll; substantially as described.
In testimony whereof I have hereunto set my hand.
